Claims.

This invention relates to a rubber ring expanding and holding tool, theprimary object of the invention being to provide a rubber ring expanderincluding a plurality of rubber supporting studs so constructed andarranged with respect to each other that the rubber ring held on thestuds will be stretched round to facilitate the application of therubber rings on animals in carrying out a particular purpose in animalhusbandry. I

Another object of the invention is to provide a ring expander whereinthe ring studs of the device will be uniformly moved with respect toeach other to spread the ring in a true circular formation and avoid thepossibilities of the instrument twisting while in use.

Still another object of the invention is to provide a centralstud-carrying rod which operates through a bearing that also providesthe support for the jaws of the tool or instrument, thereby providing astructure which is exceptionally simple in construction, light inweight, and one which is easily operated.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention consists of certain novel details ofconstruction and combinations of parts hereinafter more fully describedand pointed out in the claims, it being understood that changes may bemade in the construction and arrangement of parts without departing fromthe spirit of the invention as claimed.

Referring to the drawing Figure l is an elevational view of a rubberring expanding instrument, constructed in accordance with the invention,illustrating the ring supporting studs as expanded.

Fig. 2 is an elevational view of the instrument showing the jaws of theinstrument moved to a position with the studs disposed in position forreceiving the rubber ring to be expanded.

Fig. 3 is a sectional view taken on line 3-3 of Fig. 1.

Fig. 4 is an enlarged elevational view, one end of one jaw being shownin section, illustrating the stud supporting rods as supported therebyand extending through an opening in the end of the jaw.

Fig. 5 is a sectional view taken on line 55 of Fig. 4. I

Referring to the drawing in detail, the instrument comprises a pair ofjaws 5 and 6, the jaws having inwardly extended spaced ears I which arepivotally connected to the ears 8 that extend laterally from the tubularbearing 9, the ears 8 being supported between spaced ears I.

2 The opposite ends of the jaws 5 and 6, provide handles 9, and thesehandles are provided with enlargements Hi to which the links l l arepivotally connected as by means of the pivot pins l2.

The links I l are mounted intermediate their ends;

and have pivotal connection with the rods I3, at M, which rods extendthrough the openings formed in the ends of the jaws 5 and 6.

As clearly shown by Fig. 1 of the drawing, the

free ends of the rods 13 are bent inwardly at l6 where they are providedwith upturned ends providing studs l'l. Studs l8 extend from the jaws 6and l and cooperate with the studs I! in supporting a rubber ring.

Slidably mounted within the tubular bearing 9, is the rod l9 whichcarries the laterally extended stud 29 which is formed integraltherewith. This rod l9 has pivotal connection with the lower ends of thelinks ll, at 2!, with the result that when the handles 9' are moved fromthe position shown by Fig. 2 of the drawing, to the position shown byFig. l of the drawing, the outer ends of the jaws are expanded and therods I3 and [9 moved to positions as shown by Fig. 2, where the studscarried by the rods, are spread apart and assume a position to stretchthe rubber ring in a complete circle for positioning on an animal, tocarry out a particular purpose. In the use of. the instrument, a ring tobe positioned is placed over the studs ll, l8 and 20, and the handles 9are now moved towards each other with the result that the ring isexpanded by the action of the studs. The ring may now be held in itsexpanded position for placing over the sack or tail of the animal,thereby providing an efficient and effective means for applying rubberrings.

Having thus described the invention, what is claimed is:

1. An instrument for applying elastic rings, comprising a pair ofpivoted jaws, a tubular hearing disposed between the jaws at pointsintermediate the ends thereof, a pair of links pivotally I connectedwith the jaws, a rod pivotally connected with the links and operatingthrough the bearing, said rod terminating adjacent to the.

rated, stretching the band positioned on the studs.

2. An instrument for applying elastic rings, comprising a pair of jaws,a central tubular bearing to which the jaws are pivotally connected, apair of links pivotally connected to the jaws, a rod slidable throughthe bearing and being pivotally connected to the inner ends of thelinks, rods connected to the outer ends of the links, the latter rodsmoving through openings formed in the free ends of the jaws, ringreceiving studs formed at the free ends of the rods and jaws, and saidrods and studs being movable towards and away from each other with themovement of said handles towards and away from each other.

3. An instrument for applying elastic rings, comprising a pair ofpivotally connected members, jaws formed on the members, handles formedat the opposite ends of the members, a pair of link members pivotallyconnected to the handles the inner ends of said links being pivotallyconnected, a slidable rod pivotally connected with the inner ends of thelinks, rods connected with the'outer ends of the links, said jaws havingopenings through which the latter rods extend, the free ends of saidrods being extended laterally in the same direction providing supportingstuds, supporting studs formed on the jaws and extending in the samedirection with the first mentioned studs providing a support for elasticrings, and said handles operating to move said jaws outwardly separatingthe studs and stretching the ring positioned over the studs.

4. An instrument for applying elastic rings comprising a pair of jaws, abearing member, ears extending from the bearing member and to which saidjaws are pivotally connected, pivoted links connected with said jaws,the free ends of the links being pivotally connected, a rod slidablethrough the bearing and being pivotally connected with said links, theouter ends of the links extending beyond the outer edges of said jaws,rods extending along the outer edges of said jaws, means for pivotallyconnecting the latter arms to the links, the free ends of the latterrods passing through openings formed in the jaws, the outer ends-of saidrods being extended laterally at right angles providing supportingstuds, studs secured to the jaws, the studs of the rods and jawsextending in the same direction, providing a support for an elasticring, said rods and jaws "being movable to stretch the elastic ringsupported on the studs by inward movement of the handles of theinstrument.

5. An instrument for applying elastic rings comprising a pair of pivotedmembers, jaws formed on the members, said jaws embodying spaced flanges,a tubular bearing to which the pivoted members are connected, linkspivotally connected with the pivoted members, a rod connected with thelinks and extending through the bearing, rods connected with the outerends of the links and extending between the flanges of the pivotedmembers, the latter rods extending through openings'in the jaws, studsformed at the free ends of the rods, studs extending from the jaws, thestuds of the rods and jaws extending in the same direction providingsupports for an elastic ring, and said pivoted members being movablespreading the free ends of the rods and studs stretching an elastic ringsupported thereon. i 1 CHARLES GABEL.
